Displaying a Where-Used List from a Where-Used List 
Each object in the where-used list can be used as a component in another BOM.
How to display a where-used list for an object in other BOMs from a where-used list:
- Place the cursor on the line containing the object for which you want to display a where-used list.
- Choose Where-used list or Environment → Where-used list.
You see a list of all the BOMs in which the object is used. From this list, you can use all the active functions for a where-used list.
